Install Windows 7 on a laptop which had Windows 7 pre-installed on it?

[Ricochet J]

Hi,

My brother has a 5 year old Windows 7 Acer laptop. Windows 7 came pre-installed. It has the Windows Key/Authenticity sticker under the laptop.

Microsoft doesn't allow me to download Windows 7 OEM from their site (only retail versions). The OEM key doesn't seem to check out - it says the site is for retail versions only.

My question is simple, but I suspect the solution complicated:

How do I install fresh Windows 7 Home Premium on my brother's laptop, which came pre-installed with Windows 7?

Where do you get the Windows 7 OEM from? Microsoft don't supply it on their site.

Thanks for the link. I'll try it
